First time Ubers help please!

[Sirfetch’d]

K So I've never actually played Ubers until today I really wanted to try it out. I honestly have no idea where to start so I threw together a few Pokemon that I really liked from the tier that sounded good together. I won a few matches with it on the smogon ladder but it was really low elo so I'm not putting anything into it.

Here is my team:

Kyogre @ Blue Orb
Ability: Drizzle
EVs: 4 HP / 252 SpA / 252 Spe
Modest Nature
- Origin Pulse
- Ice Beam
- Thunder
- Calm Mind

Typical Calm Mind sweeper set for Primal Kyogre. I have heard that moving the EVs from speed to HP might be more effective? I'd like some advice there because I was a little torn here on what to do. Would 248 HP/252 Sp. Attack/4 Spe be better?

Dialga @ Leftovers
Ability: Pressure
EVs: 252 HP / 4 Atk / 252 Def
Relaxed Nature
- Stealth Rock
- Dragon Tail
- Thunder Wave
- Flash Cannon

My rocks setter, physically bulky, can force switches with Dragon Tail, can cripple with t-wave, and Flash Cannon is just for some decent hitting STAB on fairies.

Lugia @ Leftovers
Ability: Multiscale
EVs: 252 HP / 4 SpA / 252 Spe
Timid Nature
- Toxic
- Roost
- Whirlwind
- Ice Beam

Mainly added Lugia for a little bit of stall. The set is pretty basic, crippling with toxic, roosting off damage, forcing out boosted mons or threats with Whirlwind, and Ice Beam for Shaymin/Mega Mence.

Salamence @ Salamencite
Ability: Intimidate
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Return
- Outrage
- Dragon Dance
- Earthquake

I needed a good physical sweeper and Mega Mence just seemed fun to use. Hits most things pretty hard. Just your typical DD set.

Chansey (F) @ Eviolite
Ability: Natural Cure
EVs: 248 HP / 252 Def / 8 SpA
Bold Nature
- Aromatherapy
- Soft-Boiled
- Thunder Wave
- Ice Beam

Special wall/healer. I had Seismic Toss but changed it out for Ice Beam so I'm not completely ineffective vs Ghost Pokemon.

Xerneas @ Power Herb
Ability: Fairy Aura
EVs: 252 SpA / 4 SpD / 252 Spe
Modest Nature
- Geomancy
- Moonblast
- Thunder
- Focus Blast


Using Geoxern as my final Pokemon.

I'd really like some constructive advice as I honestly have no clue about Ubers(I normally only battle LC/NU/sometimes OU). I know my team lacks things such as a defogger/spinblocker. I wasn't sure how effective those were anyways. I'm all up for changing out any members of this team for anything that could fit in better over something else. As I said, I have won a few matches with this, but I also lost a few. I feel like my team could use another physical sweeper because I have nothing if Mence goes down. Thanks for the advice!

Even with a +Defense nature, Dialga is still wrecked by powerful Fighting/Ground moves. Heck, it's still wrecked by (Primal) Groudon:

252+ Atk Primal Groudon Precipice Blades vs. 252 HP / 252+ Def Dialga: 350-414 (86.6 - 102.4%) -- 18.8% chance to OHKO

Anyway, Primal Groudon is seriously good; it's incredibly versatile and it can check opposing Xerneas somewhat better, even though it doesn't normally carry moves that hit it super effectively. In the OR/AS shift, Primal Groudon took many niches that its fellow Ubers held, including Dialga's:
-Stealth Rock
-Earthquake/Precipice Blades
-Lava Plume/Stone Edge
-Roar/Thunder Wave
Nature: Relaxed
EVs: 252 HP/56 Def/200 SDef
Item: Red Orb

or
-Stealth Rock
-Precipice Blades
-Dragon Tail/Stone Edge
-Fire Punch/Stone Edge
Nature: Adamant
EVs: 224 HP/240 Atk/32 SDef/12 Spe
Item: Red Orb

Chansey's Special Attack is incredibly wimpy, meaning that it's forced to use Seismic Toss for consistent damage and Ice Beam is incredibly weak coming off of it; it doesn't even 2HKO Rayquaza for instance. Chansey has to rely on Toxic and Seismic Toss for its damage:

0 SpA Chansey Ice Beam vs. 0 HP / 4 SpD Rayquaza: 128-152 (36.4 - 43.3%) -- guaranteed 3HKO

Even if this suggestion means losing out on cleric utility, Defog Arceus isn't a bad option to consider:
-Judgment
-Defog
-Will-o-Wisp
-Recover
Nature: Timid
EVs: 248 HP/8 Def/252 Spe
Item: Spooky Plate

With Xerneas and Fairy Arceus being rather prominent threats in Ubers, it's risky to have Mega Salamence use Outrage this gen. Besides, it has Aerilate Return/Double-Edge as its source of raw power already; it outdamages Outrage:
-Dragon Dance
-Return/Double-Edge
-Earthquake/Substitute/Refresh
-Roost
Nature: Jolly
EVs: 252 Atk/4 Def/252 Spe
Item: Salamencite
Ability: Intimidate

or
-Dragon Dance
-Return
-Refresh
-Roost
Nature: Impish
EVs: 248 HP/136 Def/124 Spe
Item: Salamencite
Ability: Intimidate

Lugia's Speed is naturally high for a wall. IMO, it should focus on its bulk rather than its Speed:
-Roost
-Toxic
-Whirlwind/Dragon Tail
-Reflect/Aeroblast/Thunder Wave/Substitute
Nature: Bold/Impish
EVs: 252 HP/120 Def/136 Spe
Item: Leftovers

Blissey > Chansey because Mega Gengar. Don't forget to give your Blissey an attacking move, though (Ice Beam is recommended).

Use a 252 HP / 56 SpA / 200 SpD with a Modest nature on your Dialga, and change your moveset to Draco Meteor/Fire Blast/Roar/Stealth Rock.

Your Lugia looks good although I am not sure about that EV spread.

GeoXern: Try HP Fire over Focus Miss as it OHKOes Scizor and Ferro.

Kyogre: If you use Calm Mind, change your EV spread to 248 HP / 252 SpA / 8 Spe.

Thanks for the suggestions! Do you feel Kyogre is okay/still fits on the team after the changes? I decided to swap out Dialga for Primal Groudon because Dialga was definitely my biggest weak spot. I went for the bulkier more support set since I felt the tankiness would help more here.

Team after the changes:

Kyogre @ Blue Orb
Ability: Drizzle
EVs: 248 HP / 252 SpA / 8 Spe
Modest Nature
- Origin Pulse
- Ice Beam
- Thunder
- Calm Mind

- Aeroblast

Salamence @ Salamencite
Ability: Intimidate
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Return
- Roost
- Dragon Dance
- Earthquake

Xerneas @ Power Herb
Ability: Fairy Aura
EVs: 252 SpA / 4 SpD / 252 Spe
Modest Nature
- Geomancy
- Moonblast
- Thunder
- Focus Blast

Groudon @ Red Orb

@ArmourPearlShipper

I decided to drop both Chansey and Dialga for now to see how these changes work, but if I see I miss Chansey too much; I'll try out Blissey. I have just always preferred Eviolite Chansey but I do realize that makes me knock off bait.

I did decide to make the Kyogre EV changes though. Thanks!
